Generalize avrdude.conf on upload_flags

PlatformIO IDE
,
1

Hi,

I have a platformio.ini file that is used for programming an ATMega328p through an Arduino as ISP. I’d like to generalize this file so that upload_port and the avrdude.conf path in upload_flags are not hardcoded to my system, but rather so that there are ideally no changes made to this file across systems. Is there a way to accomplish this? Thanks in advance.

Here is my platformio.ini file:

[env:program_via_ArduinoISP]
platform = atmelavr
framework = arduino
board = atmega328p
upload_protocol = arduino
upload_port = /dev/cu.usbmodem21301
upload_speed = 19200
upload_flags =
    -C
    /Users/camerongoddard/Library/Arduino15/packages/MiniCore/tools/avrdude/7.1-arduino.1/etc/avrdude.conf
    -p
    $BOARD_MCU
    -P
    $UPLOAD_PORT
    -b
    $UPLOAD_SPEED
    -c
    stk500v1
upload_command = avrdude $UPLOAD_FLAGS -U flash:w:$SOURCE:i

So the standard file did not work at all per docs?

upload_flags =
    -C
    ${platformio.packages_dir}/tool-avrdude/avrdude.conf
    -p
    $BOARD_MCU
    -P
    $UPLOAD_PORT
    -b
    $UPLOAD_SPEED
    -c
    stk500v1
